POWER MIRROR CONTROL SYSTEM DATA LIST / ACTIVE TEST


  1. USING INTELLIGENT TESTER


    1. Connect the intelligent tester to the DLC3.

    2. Monitor the ECU data by following the prompts on the intelligent tester screen.

      Tech Tips

      The intelligent tester has a "Snapshot" function which records the monitored data. Refer to the intelligent tester operator's manual for further details.

  2. DATA LIST

    Tech Tips

    Using the intelligent tester to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time.


    1. Connect the intelligent tester to the DLC3.

    2. Turn the power switch on (IG).

    3. Turn the intelligent tester on.

    4. Enter the following menus: Body / Mirror L or Mirror R / Data List.

    5. Read the Data List according to the display on the intelligent tester.
